�Words can be separated by blanks, question marks, exclaimation marks, commas and periods (the punctuation is not to add to the length of the word). Words with apostrophes, such as ``I'm'' and ``You've'', and hyphenated words are treated as one word. For example, ``you've'' is a 5-letter word. Hyphenation may occur across two lines. �

This is all the trick of this problem another tricks is the new line separate the words if the previous letter is not hyphen (-).
